Yes and no. I think in RDF it can be very fuzzy whether or not
something inherently is a unary association. In fact, I would go
further and say that probably the reason it is difficult to define is
that there is no such thing in the real world, ie: the distinction is

In topic maps, however, there's a razor-sharp line, since it's a
question of abstract syntax. Either it was a unary association, or it
was not, and there's no ambiguity whatsoever. In this particular case
we start from topic maps, so that is not a difficulty.

In this case I'm not sure it's possible.
